IMPROVEMENT IN SEED-DRILLS.

Specilication forming part of Letters Patent No. 32,302, dated May 14,1861.

To all whom it 'may concern:

Be it known that I, JAMES S. MARSH, of Lewisburg, in the county of Unionand State of Pennsylvania, have invented anew and uselul Improvement inSeed-Planters; and I do hereby declare that the following is a full,clear, and exact description of the saine, reference being had to theaccompanying drawings, forming a part of this specification, in which-Figure l is a plan or top view of a seed-drill` with my improvementsapplied to it. Fig. 2 is a rear end View of the same, and Fig. 3 is avertical longitudinal section of the same.

Similar letters ofreferenee in each of the sev` eral figures indicatecorresponding parts.

My invention consists, first, in a new arrangement for throwing theseeding-roller out of gear and simultaneously therewith elevating thedrill-teeth.

It consists, second, in a new combination of a distributing-roller,seed-hopper, adjustable gates, and eccentrically-slotted plates.

To enable others skilled in the art to make and use my invention, I willproceed to describe its construction and operation.

A A are the wheels, B B the axles, C the frame, D the teeth, E thetransverse leverbar for raising the teeth, and E the hopper, of myimproved seed-drill. The parts named are constructed and arranged insubstantially used, except in particulars hereinafter mentioned.

'F is a distributing-roller with seed-cells a in its circumference. ltis arranged to revolve in a circular recess formed in one of thetransverse timbers of the frame, being located 4directly over thedrill-teeth land under the discharge-passages b b formed in the rearcorner of the hopper. as shown. 'lo one end of this roller a journal, G,is attachedbya loose horizontal joint, c, and on the extreme end of saidjournal is arranged a pinion, H, and the same is made to gear with thespur-wheel I, which is attached to the hub of one of the propellingwheels A, as represented. The journal is supported by and turns in a boxformed on a sliding plate, J, which has its support on a casting, K,attached to the side ofthe drill-frame, and is loosely coupled to saidcasting by means of guide-pins d d, said' pins passing up through curvedoblong slots e ein the sliding plate, as

represented. The extreme rear end of the sliding plate terminates in anopen boX, f, which receives a crank-shaped journal, g, attached to theend of the transverse drill-tooth, elevating bar E in the manner shown.

From the description given above it will be seen that when thelever-'bar E is turned up from the position shown iu black to theposition shown in red the crank-shaped journal g will cause the slidingplate J, with the journal of the pinion, to move backward, thehingejoint and slots allowing of this movement,and therefore,simultaneously with the elevation ot' the teeth, the pinion H is thrownout of gear with the spur-wheel I and the revolution of thedistributing-rollerA stopped. By turning down the bar E the pinion isagain thrown in gear, the teeth allowed to descend to the properposition for planting, and the roller set in motion.

The distributing-roller is made of chilled iron, and its cellulardistributing portions la h are cast or slipped over a small shaft, asrepresented 5 and just above each distributing portion, over each of thedischarge-passages of the hopper, a vertically-slidin g metallic gate,N, is arranged, said gates having bristles or other soft substanceattached to their lower edge for the purpose of easing the passage ot'the seed from the hopper to the distribution-roller. The gates N arearranged on the back of the hopper, and each being kept in place bymeans of a metallic guide-casting, O, and a lever-plate, P, which iscoupled to the gate by means of pin t' projecting from the gate, saidpin passing loosely through an eccentric slot cut through 'theleverplate, as represented. The upper part of each of the guide-castingsis in nearly the form of a circle, and has its surface graduated so asto gage the size of the opening through which the seed pass from thehopper.

It will be seen that by turning the leverplates in' the direction ot'the arrow the gate will be lowered by the action of the eccentric slotupon the pin and the discharge-passage decreased in size. A movement ina reverse direction increases the size of the dischargepassage. At thesame time that the passage is increased or decreased in size the upperend of the lever -plate, in combination with the graduated portion ofthe guide-castings, indicates the exact size of the passage, throughwhich the seed is escaping.

What I claim as my invention, and desire to secure by Letters Patent, is

l. The combination of the distributing-roller F, hinged journal G ofthedistributing-roller, 3. The combination of' the revolving cellusldingbearing-plate J, having curved slots e e lar distributingroller F,hopper E', sliding in it, supporting-casting K, coupling-pins d d,seed-gate N, slotted lever-plate P, and guidepinion H, spur-Wheell,lever-barE, with crankcasting O, in the manner and for the purposeshaped journal g on its end, and drill-teeth D, herein described.substantially in the manner and for the purpose set forth.

2. The combination ofthe crank-shaped journal g, slotted bearing slideor plate J, and Witnesses: hinged journal Gr, in the manner and for theGOODWIN Y. ATLEE, purpose described. G'USTAVUS DIETERICH.
